Tefzel mechanical

Water absorption of Tefzel is low (0.029% by weight), which contributes to its outstanding dimensional stabiUty as well as to the stabiUty of mechanical and electrical properties regardless of humidity. [Pg.369]

Ethylene trifluoroethylene (Tefzel) (ETFE) has good mechanical properties from cryogenic levels to 350°F (177°C). It has an upper continuous working temperature limit of 300°F (149°C). [Pg.41]

Tefzel ETFE (ethylenetetrafluoroethylene). This plastic is white, translucent, and slightly flexible. It is a close analog of the Teflon fluorocarbons, an ethylene tetrafluoroethylene copolymer. ETFE shares the remarkable chemical and temperature resistance of Teflon TFE and FEP and has even greater mechanical strength and impact resistance. [Pg.496]

The rotor seal is usually made from vespel which has the best mechanical properties and can be used in the range of pH 0-10. If the mobile phase has a higher pH a tefzel seal is needed which is pH-resistant up to pH 14. However, this material is less suited to withstand high pressures and its channels become narrower under such conditions. Tefzel surfaces are less smooth than the ones obtained by the manfacturing of vespel. Therefore it is recommended to use tefzel rotor seals only when necessary. [Pg.69]

Tefzel can also withstand temperatures of up to 80 °C, has good mechanical strength, and can be used throughout the pH range. It has an oxygen permeability of 100cm /100in -24h atm/mil at... [Pg.105]

For the separation glassy nonwovens are used. They are not expensive and yield a low resistivity. For high rate cells which are also loaded mechanically a porous foil of Tefzel is used, too, but on account of the higher resistance the deep temperature capacity is reduced. [Pg.450]
